[Solved] Kernel tool: perf ?
Juanito:
It seems the contents of libelf-dev in piCore64 are not the same as elfutils-dev in CorePure64...

Hi polikuo
Something seems wrong here:

You said this was for aarch64. Why is it looking in arch/x86 ?

I honestly don't know.
Perhaps make just traverse every directories, doing ckecks ?
I assure you I'm using aarch64
--- Code: ---tc@box:/mnt/mmcblk0p2/compile/source_code/Kernel/linux-5.4.51$ uname -r
5.4.51-piCore-v8
tc@box:/mnt/mmcblk0p2/compile/source_code/Kernel/linux-5.4.51$ uname -m
aarch64

I suspect you will need libelf from elfutils rather than libelf from http://www.mr511.de/software/

So it's your gcc being too new for that perf version. You can likely find patches to make it build with that gcc.
